DXMAPS.COM web site shows on maps or lists the most
recent contacts and
reception reports in the different amateur radio and SWL bands. Its aim is to
provide a detailed but comprehensive view of the propagation conditions in real
time.
When you browse DXMAPS for the fist time you will be presented with the
default configuration values and you will get a page like the following.
After you make your selections they will be stored in cookies so that next time
you visit the site it can restore your configuration. If it doesn't keep your
settings it can only be for two reasons:
Because your browser (or another program) is deleting
the cookies, so configure your programs so that cookies from DXMAPS.COM domain
are preserved between navigation sessions.
You are accessing using an old link / favourite / marker / bookmark pointing
to the old version. That link could contain parameters that are
forcing the default values every time you use it. Simply navigate
always to
https://www.dxmaps.com (without any
additional parameters after that) for accessing the new version. You have more
information about this issue in the FAQ page.
1.- Presentation options:
Contacts and reports can be shown in several ways:
On a map (most popular)
On a list, similar to classic DX-Cluster programs
On a band graph (time / frequency band scope)
The Chat tab gives you access to a chat where you can communicate
with other users what are also watching that selected band and area.
2.- Area selection:
These tabs allows the selection of the area you are interested in, or
"World" for getting information from everywhere in the world.
3.- Create link/shortcut:
Some users like to add shortcuts in their browsers to a certain map or
list. Clicking on the "heart" icon takes you a page where a link to the
current page is created and shown, together with additional information
about how linking works and its limitations.
4.- Band group selection:
Click on one of the two tabs to select the band group you are interested
in. "LF - HF" for bands below 30 MHz and "VHF & up" for bands above 28 MHz.
Notice that the 10 meter band , being it the frontier between HF and VHF, is
shown in both band groups.
5.- Map type:
This was a Google Maps feature and it is no longer available in version
4.x that makes use of OpenStreetMaps
6.- Information window:
This is the area where additional information is shown when you click
somewhere on the map or search information on a callsign, grid square, IOTA,
etc. Depending on whether you click on a callsign or on blank area of
the map the information shown can be different.
7.- Band selection:
These tabs allow you to select the band you are interested in and they
are different depending on the band group you have selected.
For "VHF
& UP" apart from the bands themselves there are also other tabs, like the
VHF propagation ticker or the "MUF ES" option for showing an estimation of
the current Sporadic-E MUF situation.
For ยท"LF - HF" there is also and additional tab for the DX news ticker.
8.- Layer selection:
You can choose the maps to be overlaid with one of the following layers:
Magnetic equator: Shows the location of the geomagnetic equator and
tropics that affect north to south propagation and specially Transequatorial (TEP).
Grey line: Shows the terminator line, useful for determining the
areas where grey line propagation is possible, and also the area
illuminated by the sun.
Moon footprint: Shows the area where the Moon is currently visible,
specially intended for those interested in EME. For more detailed Moon
calculations you can use the
on-line EME calculator.
VOACAP prop (SP): For bands between 3 and 30 MHz it will show the
estimated propagation situation from your location in the selected band
by the Short Path. Dark areas mean that no propagation is expected.
It requires that you are logged in, in order to know your location.
Calculations are made using the VOACAP model and due to the huge amount
of data calculated , transferred and drawn it will take a while until
you get the overlay actually painted, not less than 15 or 20 seconds in
the best of the cases (fast PC and fast internet connection). Good
news is that this delay is only noticeable right when you select the
option. If you leave the map open it will be updated
automatically.
VOACAP prop (LP): Same than the former layer, but for Long Path
propagation.
Aurora forecast: Shows the NOAA 30 min Aurora forecast.
Source
data belongs to the National Oceanic & Atmospheric Administration
(NOAA).
Colour codes are used to indicate the probability of visual aurora:
Light green: 20-35%
Green: 35-50%
Light orange 50-70%
Orange: 70-85%
Red: 85-100%
Time zones: Show the different time zones.
CQ zones: Show the CQ zones (WAZ).
In order not to make the maps unreadable with too much information,
layers are exclusive. This means that when you select a layer, the rest are
deselected.
If you leave the map open, the layer will be redrawn automatically when
there is an update. There is no need you press F5 or refresh the map
manually.
Here you can customize what information is shown on the maps/lists and
how it is shown. You can select (tick) several options at the same time but
you will possibly want to limit their number in order not to get the map
overcrowded. To deselect an option simply click on it again. Selected options
are indicated by the "tick" character.
Only DX-Cluster: If this option is selected, only the spots which
source is the DX-Cluster will be shown. Use it if you are not interested
in automated reports as from the Reverse Beacon or WSPR Networks.
PSK reporter: If this option is selected, the spots which
source is the PSK Reporter will also be shown. Don't select it if you
are not interested in automated reports as from the PSK Reporter Network.
(PSK Reporter spots are available thanks to the
DK1MAX PSK-Reporter
cluster)
Grid squares: Shows the grids squares / locators. The
level of detail (2 or 4 character squares) adapts automatically
depending on the zoom level chosen.
Grid squares thin: Same that the above, but lines and grid squares
names are thinner.
Prefixes: Show the most usual amateur radio prefixes of each
DXCC entity.
Continents: Show the continental boundaries, according to the WAC
(Worked all continents) award.
Labels/roads: Show geographical names and roads on the maps. This is a feature
of OpenStreeMaps and the level of detail depends on the Zoom Level.
Callsigns: Show the callsigns of the stations involved in the
contacts/reports shown on the maps.
Small map: Shows a smaller map canvas, for users with low
resolution monitors, tablets, etc.
Only last 15 min: Only the reports of the last 15 minutes will be
shown, instead of the last 60 min.
Only > 2600 km / 1600 mi: Only the reports above 2600km (aprox.
1600 mi) will be shown.
Mouse wheel zoom: When this option is selected the maps can
be zoomed using the mouse wheel. (It will be shown only for non touch
screen devices)
Move with 2 fingers: When this option is selected the use of
two fingers is required to move and zoom the maps, also affecting page
scroll behaviour. Enable or disable it according to your preferences. (It will be shown only for touch screen devices)
MUF indep.of mode: This option allows to configure how you
want the MUF map to be built. If ticked the MUF map will show the
maximum of information, independently of the mode of the QSO/SWL used to
generate it. Otherwise only the QSO/SWL that match the modes you
have selected will be taken into account.
Hide callsign info: When this option is selected, the message
box with the last report that appears when you hover on a callsign will
not be shown.
Callsigns in bold: When this option is selected, the
callsigns will be shown in bold on the maps.
The options "Only DX-Cluster" and "Only > 2600 km" affect both the maps and lists. The
rest only apply to the maps.
Allows you to filter by the mode or modes that you are interested in (CW,
Phone, Digital, WSPR). If you have selected band group "VHF & up" it also allows
to filter by the propagation modes you are interested to track (Aurora, EME,
MS, Tropo, etc.)
B.- Filter and Search input box:
This is an input box where to enter a callsign or continent you want to filter or a text (callsign, locator, IOTA, etc)
you want to search (see below)
C.- Filter by callsign:
Enter a callsign or continent code (NA, EU, SA, AF, OC, AS) in B and click this icon to set a filter by it.
Only spots / reports containing that callsign or related to that continent will be shown both in the maps
and lists. Use it to see your spots, or who is spotting you. Another use is,
for instance, to see who is working, or in which bands, a certain DXpedition.
When filtering by continent you will only see the spots of stations from
stations in that continent or those making QSO with that continent.
You can also use the * (asterisk) wildcard to filter callsign patterns.
Some examples are:
EA6* Only stations which
callsign begins with EA6
*VQ Only stations which
callsign ends with VQ
*A6V* Only stations which
callsign contains characters A6V
When filtering is enabled the icon will show a red tick and the input box
will be disabled. Click on the icon again to disable the filtering.
When the filtered callsign has an online
log, the QSO from his log will also be shown.
Enter the text that you want to search/locate in B and click this icon
to start the search. You can search a callsign, a grid square, an IOTA
reference (format XX-NNN) or even a geographical name (town, province,
island name, etc.).
When search mode is enabled the icon will show a red tick and the input
box will be disabled. Click on the icon again to disable the search mode and
go back to the normal map.
This is the area where the map/list will be shown, depending on the
option you select.
You can drag and zoom in and out the maps as you do with any other Maps. Your customized visible area will be stored for each map area in
cookies, so that next time you visit DXMAPS you won't have to configure it again.
You can also right-click on the map and a pop-up menu will appear with
some options/functions (in tablets and mobile phones you can click on the map with your finger
and keep the pressing for a couple of seconds to simulate the right-click of
a mouse)
Notice that the show/hide options are for temporarily use. For selecting
the option permanently you have to do it with the layer/options selections
(see 8 and 9)
You can click on a callsign on the map to get more detailed information
and links regarding it. If you click anywhere else you will get more
information on that location in the Information Window (6). Clicking
on a callsign can be cumbersome until you get used to it. Place the
end of the index finger of the hand cursor near the middle of the callsign and
then click.
You can right click on a callsign and select the "Recent reports of this
station" option to quickly get a listing of the most recent reports of it.
Enter a callsign in B and click this icon to hide a certain callsign.
Spots / reports containing that callsign will not be shown on the maps
and in the lists. Use it, for instance, to hide the spots of a pirate
station.
When hiding is enabled the icon will show a red tick and the input box
will be disabled. Click on the icon again to disable the hiding.
